37172989 divided by 85 
Our goal is to divide 37172989 by 85.

Going ahead to step 1:
85 goes into 3 0 times with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Grab the next digit (7) from the dividend, add it to 3, then carry on: 37 / 85

Let's proceed to step 2:
37 divided by 85 is 0 with a remainder of 37.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 37, we get 37.
Include the next digit (1) from the dividend after 37, then repeat: 371 / 85

On to step 3:
The number 85 fits into 371 4 times, leaving a remainder of 31.
Use 4 as the next digit of our solution. 
Result so far: 4.0
If we subtract 340 from 371, we get 31.
Grab the next digit (7) from the dividend, add it to 31, then carry on: 317 / 85

Step 4:
If we divide 317 by 85, we get 3 and a remainder of 62.
Write down 3 as next digit of the result. 
Result so far: 43.0
If we subtract 255 from 317, we get 62.
Bring next digit (2) of the dividend behind the 62 and repeat the process: 622 / 85

On to step 5:
85 can be fit into 622 7 times, resulting in a remainder of 27.
The number 7 becomes the next digit in our result. 
Result so far: 437.0
The remainder is 27 after subtracting 595 from 622.
Fetch the next digit (9) from the dividend, attach it to 27 and continue: 279 / 85

Step 6:
If we divide 279 by 85, we get 3 and a remainder of 24.
Put 3 as the next digit of the answer. 
Result so far: 4373.0
The remainder is 24 after subtracting 255 from 279.
Grab the next digit (8) from the dividend, add it to 24, then carry on: 248 / 85

On to step 7:
85 can be fit into 248 2 times, resulting in a remainder of 78.
Write down 2 as next digit of the result. 
Result so far: 43732.0
If we subtract 170 from 248, we get 78.
Include the next digit (9) from the dividend after 78, then repeat: 789 / 85

Step 8:
When dividing 789 by 85, we get 9 with a remainder of 24.
The next digit of our result is 9. 
Result so far: 437329.0
Subtracting 765 from 789 leaves us with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

On to step 9:
85 can be fit into 240 2 times, resulting in a remainder of 70.
Record the quotient 2 as the next digit in the result. 
Result so far: 437329.2
Subtract 170 from 240 to get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Going ahead to step 10:
The number 85 fits into 700 8 times, leaving a remainder of 20.
Write down 8 as next digit of the result. 
Result so far: 437329.28
If we subtract 680 from 700, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 11:
The number 85 fits into 200 2 times, leaving a remainder of 30.
Write down 2 as next digit of the result. 
Result so far: 437329.282
Deduct 170 from 200 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 12:
If we divide 300 by 85, we get 3 and a remainder of 45.
The number 3 becomes the next digit in our result. 
Result so far: 437329.2823
The remainder is 45 after subtracting 255 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Let's proceed to step 13:
85 can be fit into 450 5 times, resulting in a remainder of 25.
Use 5 as the next digit of our solution. 
Result so far: 437329.28235
If we subtract 425 from 450, we get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Advancing to step 14:
250 divided by 85 is 2 with a remainder of 80.
Use 2 as the next digit of our solution. 
Result so far: 437329.282352
Subtract 170 from 250 to get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Let's proceed to step 15:
The number 85 fits into 800 9 times, leaving a remainder of 35.
Record the quotient 9 as the next digit in the result. 
Result so far: 437329.2823529
Subtract 765 from 800 to get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Step 16:
The number 85 fits into 350 4 times, leaving a remainder of 10.
Use 4 as the next digit of our solution. 
Result so far: 437329.28235294
Subtract 340 from 350 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

The final outcome is 437329.28235294, with a leftover of 1e-08.
